HK Standard System

Traditional insulated sandwich panels, comprised of a thin fascia wythe, insulation and a much thicker structural wythe would typically fall into this system. This system is comprised of our HK Standard non-conductive wall tie and any type of desired rigid insulation.

This system is designed to create a non-composite insulated concrete sandwich panel. This allows the two wythes of concrete to be tied together with a non-conductive wall tie but still allow the two layers to shrink or expand independently of one another using the tie for deflection.

Holds a face wythe of concrete affixed to the panel without the need for thermally inefficient metal connectors or solid concrete sections

* All Standard Ties can be made in 0.25 inch increments depending on project design and specifications.

Testing Standards

The HK Standard ties are tested in accordance with the ICC-ES AC 320. The table below displays the testing comparisons of some of our popular Standard ties. You can view more complete testing reviews for each tie on their individual product pages.

About HK™ Composites

HK Composites creates several types of HK Wall Ties for use in insulated concrete sandwich panels. The ties (also known as "spikes" or "connectors") are manufactured from high-performance, heat and alkaline resistant, engineered polymers.

HK ties minimize the energy draining effects of thermal bridging experienced when metal ties or solid concrete sections are used to connect the concrete wythes of sandwich panels through the insulation layer. The use of HK low-conductivity ties results in a sandwich panel with maximum thermal performance.
